Azeotrope Definition and Examples

Azeotrope Definition and Examples An azeotrope is a mixture of liquids that maintains its composition and boiling point during distillation. It is also known as an azeotropic mixture or constant boiling point mixture. Azeotropy occurs when a mixture is boiled to produce a vapor that has the same composition as the liquid. The term is derived by combining the prefix a, meaning no, and the Greek words for boiling and turning. The word was first used in a publication by English chemists John Wade (1864–1912) and Richard William Merriman in 1911. In contrast, mixtures of liquids that do not form an azeotrope under any conditions are called zeotropic. Types of Azeotropes Azeotropes may be categorized according to their number of constituents, miscibility, or boiling points: Number of Constituents: If an azeotrope consists of two liquids, it is known as a binary azeotrope. An azeotrope consisting of three liquids is a ternary azeotropes. There are also azeotropes made of more than three constituents.Heterogeneous or Homogeneous: Homogeneous azeotropes consist of liquids that are miscible. They form a solution. Heterogeneous azeotropes are incompletely miscible and form two liquid phases.Positive or Negative: A positive azeotrope or minimum-boiling azeotrope forms when the boiling point of the mixture is lower than that of any of its constituents. A negative azeotrope or maximum-boiling azeotrope forms when the boiling point of the mixture is higher than that of any of its constituents. Examples Boiling a 95% ethanol solution in water will produce a vapor that is 95% ethanol. Distillation cannot be used to obtain higher percentages of ethanol. Alcohol and water are miscible, so any quantity of ethanol can be mixed with any quantity to prepare a homogeneous solution that behaves like an azeotrope. Chloroform and water, on the other hand, form a heteroazeotrope. A mixture of these two liquids will separate, forming a top layer consisting mostly of water with a small amount of dissolved chloroform and a bottom layer consisting mostly of chloroform with a small amount of dissolved water. If the two layers are boiled together, the liquid will boil at a lower temperature than either the boiling point of water or of chloroform. The resulting vapor will consist of 97% chloroform and 3% water, regardless of the ratio in the liquids. Condensing this vapor will result in layers that exhibit a fixed composition. The top layer of the condensate will account for 4.4% of the volume, while the bottom layer will account for 95.6% of the mixture. Azeotrope Separation Since fractional distillation cannot be used to separate components of an azeotrope, other methods must be employed: Pressure swing distillation applies pressure changes to change the composition of a mixture to enrich the distillate with the desired component.Another technique involves the addition of an entrainer, a substance that alters the volatility of one of the azeotrope components. In some cases, the entrainer reacts with a component to form a nonvolatile compound. Distillation using an entrainer is called azeotropic distillation.Pervaporation involves separating components using a membrane that is more permeable to one constituent than the other. Vapor permeation is a related technique, using a membrane more permeable to the vapor phase of one component than another. Source Wade, John, and Richard William Merriman.

The Fundamentals of the Intertropical Convergence Zone

The Fundamentals of the Intertropical Convergence Zone Near the equator, from about 5 degrees north and 5 degrees south, the northeast trade winds and southeast trade winds converge in a low-pressure zone known as the Intertropical Convergence Zone (ITCZ). Solar heating in the region forces air to rise through convection which results in the accumulation of large thunderstorms  and plethora of  precipitation, spreading rain around the Equator year-round; as a result of this, combined with its  central location on the globe, the ITCZ is a key component of the global air and water circulation system. The location of the ITCZ changes throughout the year, and how  far from the equator it gets is largely determined by the land or ocean temperatures underneath these currents of air and moisture- otter oceans yield less volatile change while varying lands cause varying degrees in the ITCZs location. The Intertropical Convergence Zone has been called the doldrums by sailors due to the lack of horizontal air movement (the air rises with convection), and its also known as the Equatorial Convergence Zone or Intertropical Front. The ITCZ Doesn't Have a Dry Season Weather stations in the equatorial region record precipitation up to 200 days each year, making the equatorial and ITC zones the wettest on the planet. Additionally, the equatorial region lacks a dry season and is constantly hot and humid, resulting in large thunderstorms formed from the convectional flow of air and moisture. The precipitation in the ITCZ over land has whats known as a  diurnal cycle  where clouds form in the late morning and early afternoon hours and by the hottest time of the day at 3 or 4 p.m., convectional  thunderstorms form and precipitation begins, but over the ocean, these clouds typically form overnight to produce early morning rainstorms. These storms are generally brief, but they make flying quite difficult, especially over land where clouds can accumulate at altitudes up to 55,000 feet. Most commercial airlines avoid the ITCZ while traveling across continents for this reason, and while the ITCZ over the ocean is usually calmer during the day and night and only active in the morning, many boats have been lost at sea from a sudden storm there. The Location Changes Throughout the Year While the ITCZ remains near the equator for most of the year, can vary in as much as 40 to 45 degrees of latitude north or south of the equator based on the pattern of land and ocean beneath it. The ITCZ over land ventures farther north or south than the ITCZ over the oceans, this is due to the variations in land and water temperatures. The zone mostly stays close to the Equator over water. It varies throughout the year over land. In Africa in July and August, for instance, the ITCZ is located just south of the Sahel desert at about 20 degrees north of the Equator, but the ITCZ over the Pacific and Atlantic Oceans is usually only 5 to 15 degrees North; meanwhile, over Asia, the ITCZ can go as far as 30 degrees North.

He wanted the customer to feel more connected to his business. Therefore, he establishes an online shop to make it easy for the customer to shop. Nowadays there are many ways for business owners to advertise their products. One of these ways is the electronic advertisement that has advantages and disadvantages. Knowing these advantages and disadvantages will help business owners to choose the best way for them to advertise their products. We all know that an electronic advertisement is a new way in the business world, and it is an unfamiliar way for many people. This reason caused most of the electronic advertising drawbacks. Another reason is peoples satisfaction with the traditional way of advertising."Technology has still not advanced enough to allow electronic advertising to compete with television and print"[1]. In order for an electronic advertisement to be successful, the technology has to improve but in these days we didn't reach a high level of technology development. Even though if technology has developed, many people won't have the ability to explore the online information system. On the other hand, people who have the skill to use the online information system find electronic advertisement distracting and annoying. Therefore, they try to avoid visiting website that has the advertisement for it. Moreover, most of the advertisers tend to use the traditional way to advertise because they find electronic adve rtisement is not appealing to them.And that what help television and print advertisement to have a huge market with much attraction from advertisers.

Investment in the Indian Education Sector Essay Example for Free

Investment in the Indian Education Sector Essay Education is the key to unlocking and building lasting value in a robust economy. For any country to grow and prosper, a well-positioned educated young population is the fundamental requirement to meet the demands of an increasingly global economy and productive value creation. India has amongst the largest student population in the world and a low literacy level of 74. 04% (2011)1. According to census 2011 figures, over 35. 3% of the 1. 21 billion people are between the age group 0-14 years. Additionally, there is shortage of employable manpower in various industry segments. In order to meet this existing and emergent demand, there is huge need of investments in the Indian education sector. Currently, education is primarily handled by the government through its infrastructure and budget outlays. But given the small budget outlays and complex regulatory structure, supply is lagging far behind the demand of education.

Being in â€Å"Concurrent list†, education is being governed by both Central and State government with huge variations amongst the state regulations. Currently, the government regulates who you can teach, what you can teach them and what you can charge them. Some of the key bodies regulating education in India are:? Schooling o Department of School Education and Literacy MHRD o Central Board of Secondary Education (CBSE) o Various State Boards o National Council of Educational Research and Training (NCERT) 1 Census of India, 2011 Page 3 A research report on Investment in Indian Education Sector ?

Bar Council of India (BCI) ? National Council of Teacher Education (NCTE) Voluntary Education and Skill Development o National Council for Vocational Training (NCVT) o National Skill Development Corporation (NSDC) ? In order to overcome this overlapping nature of various governing bodies especially in higher education, government is planning to come up with National Commission for Higher Education and Research (NCHER). This commission would work as a single regulatory body which would determine, co-ordinate and maintain standards in promotion of higher education and research. It will subsume regulatory bodies such as UGC, NCTE and AICTE, thus making the process more streamlined. KEY POLICY/ACT ?

With economic growth and enhanced technology it has become necessary to develop the Indian education sector. Funds are a major concern in the market to meet this demand. The government has taken many initiatives for the development of education infrastructure which needs to be supplemented led by private players. The government has also opened the doors for foreign universities by passing Foreign Educational Institution (Regulation of Entry and Operation) Bill, 2010, which will help in shaping the education industry structure specially pertaining of higher education in India. A research report on Investment in Indian Education Sector About 185,000 Indians study overseas and spend USD 4 billion annually. This is almost 10% of the private spend on education, coming from a very small 0. 001% segment of the student population. A number of these students are now returning to India after completing their studies, as job markets in India are more attractive, especially in contrast to weak macro scenarios in the western markets. Entry of leading foreign institutions will enable some of this USD 4 billion spend to stay in India, and also provide a much needed boost to quality. STRUCTURE Indian education system can be divided into formal and informal segments which are further divided into sub-segments. Formal education segment broadly comprises schools and higher education institutes. Schools often classified as K-12(Kindergarten to 12th) caters to ‘3-17 years’ age group. While higher education includes graduate, diploma, professional and post-graduation courses caters to ’18-22 years’ and above age group. On the other hand, informal education segment comprises of preschools, multimedia, ICT, vocational training, books and coaching classes. This segment is free from regulation as opposed to highly regulated formal education segment. Schools (K-12) Formal Higher Education Preschools Indian Education System Multimedia ICT Non-formal Vocational training Books Coaching classes Page 5 A research report on Investment in Indian Education Sector INTERNATIONAL SCHOOLS India is home to several well acclaimed International Schools and is increasing rapidly. This demand has been fuelled by parents looking for a new system of education which is more interesting and less stressful. Also, large number of NRIs resettling in India is also contributing to this demand. Being in India these schools have to adhere to certain requirements of the Indian national system irrespective of the examination system adopted by them. Most of the international schools opt for the International Baccalaureate (IB) Board. However, there are other examination systems like the General Certificate of Secondary Education (GCSE) and General Certificate of Education (GCE) examination systems which are also present. The IB is a recognized leader in the field of international education. It is a non-profit, mission-driven foundation that offers three programs for students aged 3 to 19. ? ? ? Primary Years Programme (PYP) Middle Years Programme (MYP) Diploma Programme -For students aged 3 to 12 -For students aged 11 to 16 -For students aged 16 to 19 In India, most international schools offer IB Diploma Programme. In this students study six courses at higher level or standard level. Students must choose one subject from each of groups 1 to 5, thus ensuring breadth of experience in languages, social studies, experimental sciences and mathematics. The sixth subject may be an arts subject chosen from group 6, or the student may choose another subject from groups 1 to 5. Additionally, the programme has three core requirements that are included to broaden the educational experience and challenge students to apply their knowledge and understanding. The â€Å"extended essay† is a requirement for students to engage in independent research through an in-depth study of a question relating to one of the subjects they are studying. â€Å"Theory of knowledge† is a course designed to encourage each student to reflect on the nature of knowledge by critically examining different ways of knowing (perception, emotion, language and reason) and different kinds of knowledge (scientific, artistic, mathematical and historical). â€Å"Creativity, action, service† requires that students actively learn from the experience of doing real tasks beyond the classroom. Students can combine all three components or do activities related to each one of them separately. Some of the International Schools in India:? ? ? ? ? ? ? ? ? ? ? ?

However, inadequate infrastructure has placed pressure on the sector’s overall development. Education sector is unable to cope with growing market demand and global competition due to constrained investments. Increased private investment is imperative to expand infrastructure and provide greater access to quality education. Also, Government is planning to set up an education ? nance corporation with an investment of around US$4–5 billion, which aims to provide the education sector with long-term, low-cost ? nancing. PUBLIC PRIVATE PARTNERSHIP (PPP) PPP can provide the much needed finance to the education sector while serving as an efficient operating model.

Americas Desire to Enter into World War I Essay -- America and World

World War I, known as the Great War prior to World War II, was a global war which began in Europe on July 1914 and ended on November 11, 1918. The Central Power, Germany, Austria-Hungary, and Italy, were at war with the Allies, Great Britain, France, and Russia. These alliances posed a threat when Archduke Franz Ferdinand, heir to the Austro-Hungarian Empire, was assassinated by a Serbian nationalist; at this time, Germany urged the Austro-Hungarian Empire to reciprocate and Serbia turned to Russia for help. A chain reaction began and soon Europe was entangled in a world-wide war. In 1917, the United States entered the war, joining the Allies due to issues with Germany, despite supposed reluctance. Woodrow Wilson, the President of the United States throughout the duration of World War I, proved through foreign policy from 1914-1917, the United States’ citizens’ and governments’ evident desire for war from April 1917 to November 1918, and the United Statesâ€⠄¢ domestic effects from the war from April 1917 to 1919 that the United States was eager to enter World War I. President Wilson asserted in 1917, â€Å"I think that you will agree with me that, in view of this [submarine] declaration†¦this Government has no alternative, consistent with the dignity and honor of the United States, but to take the course which†¦it announced that it would take†¦Ã¢â‚¬ . Wilson asked Congress to declare war on Germany, and so it happened. President Wilson’s alleged ‘neutrality’, the Preparedness Act and war declaration were foreign policies executed in the United States from 1914-1917 that validate the fact that the government, as well as American citizens, was eager to enter World War I. In 1914, President Woodrow Wilson declared neutrality in the United Stat... ...ight in World War I through Woodrow Wilson’s unwilling demonstration of American foreign policy from 1914-1917, the American desire for war from April 1917 to November 1918, and the domestic effects in American from the war from April 1917 to 1919. World War I helped the United States achieve a boom in its economy before the Great Depression and strengthened ties between the members of the Allied Powers.

Design Activities and Environments Essay

1. Review the definitions of architectural and detailed design and the brief descriptions of high-level design activities at the beginning of the chapter. Which activities are clearly architectural? Which are clearly detailed? Which can be architectural or detailed? Designing the support services architecture and deployment environment and designing the software architecture are clearly architectural. Designing use case realizations and designing the database are clearly detailed. Designing the system and user interfaces and designing the system security and controls can be architectural or detailed. 2. Discuss the evolution of client-server computing from file server to multilayer applications to Web-based applications. What has been the driving force causing this evolution? Where do you think network computing will be in the next five years? Ten years? Cheaper computers, and networks, ubiquitous networking, and the desire of companies to increase the accessibility of their systems to increase the customer base/satisfaction, gain efficiencies from greater inter- and intraorganization coordination, and greater flexibility to reorganize people, processes, and systems. 3. Assume that the deployment environment for a high-volume payment processing system consists of the following: †¢ DB2 DBMS running under the OS/390 operating system on an IBM S/390 mainframe †¢ WebSphere application server running under the Z/OS operating system on an IBM zSeries 900 mainframe †¢ CORBA-compliant component-based application software written in Java that will be executed by other internal and external systems What are the key architectural design decisions that must be made for the system? When should the decisions be made and who should make them? Outline the subsequent design tasks that should occur after the key architectural design decisions are made. To what extent can the subsequent steps be performed in parallel? Some key architectural decisions to explore include: the key components and subsystems, where each component will execute and how will all of the pieces interoperate (which requires nailing down how the network, CORBA, and database infrastructure will be configured)? Many of the decisions depend on whether the supporting infrastructure is already in place. If it is, then many of the architectural decisions can be delayed until much code has been written and tested. If not, then the required infrastructure and tools will have to be acquired and configured. Developers will have to be trained, and architectural design will need to occur early to ensure that the developers don’t make any â€Å"mistakes† due to lack of fit with the development or deployment environment. Note that an OO development approach is assumed given the nature of the infrastructure and tools 4. Develop a network diagram that supports the architectural design decisions in your answer to number 2. Answers will vary. Some important points that should be included are: File servers just sent the data across the network. They tended to use lots of bandwidth, because the entire file was sent. Also, since the applications that processed the data were on all the different workstations, deployment and maintenance of these applications was expensive. Application servers moved the applications from the workstations (clients) to the server. This made it easier to maintain a consistent set of applications and to upgrade the applications. This movement was influenced by the appearance of â€Å"thin clients† that had very little storage, but good processing capability. However, due to the drastic reduction in storage costs, thin clients have not caught on. Multi-tier networks are where multiple servers and clients work together to provide the complete functionality of a system. Some processing will be on the clients. Servers such as database servers and application servers provide additional capability. The driving force behind much of this is the rapid growth and capability of the Internet and languages such as JAVA with protocols such as J2EE. Microsoft’s .NET also provides capabilities to have distributed systems. Answers for the future will vary.

Native English Teachers Essay Example | Topics and Well Written Essays - 750 words

Native English Teachers - Essay Example It has been seen that there are problems with the varying standards for native speakers teaching in higher education in foreign countries. The main issue is the acceptance of a criteria for standardization and qualifications necessary for teaching English. Further, once the standards are established, there is a need to define a process for assessing the English teachers' performance and qualifications. Also, the English teachers' professional growth and career development are needed to be defined and actively pursued by the school authorities. The current study is therefore aimed at evaluating the standards and qualifications of English Teachers and in assessing what are the current and future gaps in qualifications and requirements. Native English speakers are increasingly facing challenges due to the globalization of the language. English is no longer one language or a language owned by one country alone.

English is used not only with different accents but with innumerous nuances and local additions to it. Under the circumstances, there is a need for the Native English teachers to move away from the mindset of being a simply a teacher of the language to become some one who himself learns the concepts and traditions of the local people. Thus, an immediate requirement for the Native English teacher trainings is to include content on local usage of English, as well as on the local cultural and social environment. This requirement can however be met only by the consent of the authorities who develop and sanction training and content material for the English teachers, and this may require time spent on obtaining field data or in evaluating the scope of such an approach. However, there is another approach that the teachers themselves can follow in order to be able to teach better in a global educational environment. This is by adopting a reflective approach to teaching instead of using a
